Is Lemon Curd Keto?
Regular lemon curd is not keto (so much sugar), but this easy low carb lemon curd is keto friendly! Each tablespoon serving has just 1/2 gram of net carbs.
For the smoothest lemon curd, the sweetener makes a huge difference! That’s why this recipe uses Besti Monk Fruit Allulose Blend. It dissolves effortlessly into the lemon curd, so it’s never gritty — with no added net carbs!
Ingredients & Substitutions
Here I explain the best ingredients for my sugar-free lemon curd recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Butter – Use unsalted.
- Lemons – You’ll need about 3-4 whole lemons, as we’re using both fresh lemon juice and zest.
- Egg Yolks – Using the yolks only gives this lemon curd a luxurious texture. Make sure they are at room temperature before you begin. Save the whites and make a keto lemon meringue pie or keto bread!
- Besti Monk Fruit Allulose Blend – The best way to have all the sweetness of sugar without the sugar and carbs. Unlike other sweeteners (including erythritol and other brands of monk fruit sweetener), Besti dissolves completely and won’t crystallize, which is why it’s the only one I recommend for this sugar free lemon curd recipe. It’s also fine to use Besti Powdered — both versions dissolve easily.
- Sea Salt – To balance the sweetness.

1Horrible. Did not thicken and was really sour.
Wholesome Yum D
1Hi Ivy, Did you follow the recipe as written?
Judith Bell
1Easy and delicious! A great way to use the surplus meyer lemons we have this time of year.
Vit
1It was a perfect match to the vanilla ice cream 🙂 I’m a big fan of ice cream, so I made this sugar free lemon curd since there is already so much sugar in ice cream.
Katie Crenshaw
1Oh wow! This lemon curd is bursting with flavor! It is such a lovely treat without the sugary guilt!
Patricia Farrell
1Excellent instructions my grandchildren love it and it turned out really good and tastes great. Thank you Patricia
Pamela Ebertz
1Could I can this recipe? Instead of keeping it in the refrigerator?
Maya | Wholesome Yum
0Hi Pamela, Yes, I think you can, but I have not tried it.
Marcia
1Can I use powdered stevia?
Maya | Wholesome Yum
0Hi Marcia, I don’t recommend stevia as it has an aftertaste. Also, pure stevia doesn’t have the bulk/volume that Besti does, and if you use a stevia blend, these typically don’t dissolve properly.
Tami Proctor
1Lemon Curd is one of my favorites! Thank you for the recipe it’s delicious!
Lana McQuown
1I made this curd to go with a lemon meringue chaffle. It was delicious with the perfect balance of sweet and tartness. I can’t believe how easy it was to make. I can see it being used it all kind of other recipies. Thanks for creating such wonderful recipes.
Loreto and Nicoletta
0Hi Maya, this is a great take on lemon curd with a keto twist!??❤️ Great tip on sweetness to use and this curd is so versatile, however, one of my favorites is lemon meringue! Thanjs for sharing!❤️❤️??
Barbara
1If I use less monk fruit, will that affect consistency?
Maya | Wholesome Yum
1Hi Barbara, It might, I haven’t tried that!
Nancy
1Hi Maya! This looks delicious! I’m ready to try this after having gathered about a dozen fresh lemons from my friends’ tree in California! Quick question: how would straight liquid monk fruit work? I like this because it’s cleaner and there’s no issue with grittiness or fiber at all. Have you tried this option at all?
Maya | Wholesome Yum
1Hi Nancy, We don’t recommend a liquid sweetener in this recipe, as it would be too runny. There is no fiber in Besti.
Dee
1About how long will the Lemon Curd keep in the fridge?
Maya | Wholesome Yum
1Hi Dee, It will keep in the fridge for 1-2 weeks.
Terra
1Hi Maya! Appreciate the email today about Fruity keto recipes for spring and plan on making both the sorbet and lemon curd. May be a dumb question, but wondering if straining the seeds out (for diverticulosis) would change the macros from keto to low carb since I’d be removing fiber? Also, while I can figure out how to swap other berries, what would you suggest to make lemon or lime sorbet or sherbet. Thanks for all you do!!
Maya | Wholesome Yum
1Hi Terra, Straining out seeds would remove fiber, but it would also remove the component of total carbs contributed by the fiber, so the net carbs should stay about the same. We haven’t experimented with a lemon or lime sorbet yet.
Laurie S Burke-Deutsch
1Can this recipe be made thick enough to use as a pie filling? Thank you. This sight is fantastic!!!
Maya | Wholesome Yum
1Hi Laurie, It’s a little thin for a pie filling. You can see a modified version used for this keto lemon meringue pie recipe.
Nellie Tracy
1This is a great lemon curd recipe! So delicious!
Britni
1I still can’t believe this is sugar free, it was soooo good! I’ll never use a regular lemon curd recipe again!
Carol L
0Can this be frozen?
Maya | Wholesome Yum
0Hi Carol, Yes, absolutely!
Barb
0Was wondering if this can be canned?
Maya | Wholesome Yum
0Hi Barb, No, I would not do that with a recipe containing fresh egg yolks.
Angela Hamby
0This Lemon Curd is great!
Maya | Wholesome Yum
0Thank you, Angela! Enjoy!
Judy M
0I used to love your lemon curd. But I had to become dairy free. Can this be made with either plant based butter or butter flavored coconut oil? Thank you very much.
Maya | Wholesome Yum
0Hi Judy, I’ve only made this recipe with regular butter, but I’m pretty sure it would work with a solid plant based butter (not a spread). Let me know how it goes if you try it.
